Historically, this has happened a few times. YouTube decides on a scheme, and PrE is written around that, then released. At a point, after PrE was released, YouTube changes things, like extended accounts, that did not exist, when PrE was being written. This has been going on for a long time.
Once, just getting output for YouTube was difficult, as they changed what they needed, and what they did with the footage, with great regularity. It was like playing football, but with moving goalposts.
When something new, like extended accounts, is introduced, until the next version of PrE, the only workaround to accommodate those YouTube changes, is just as Steve recommends.
Good luck,
